Abstract: Provided are an apparatus for displaying a holographic image and a method of controlling the apparatus. The apparatus for displaying the holographic image includes a controller, a light source, an optical system, a spatial light modulator, a filter, an electric optical scanner, a multi-channel projection optics, and a screen. The spatial light modulator modulates a light beam passing through the optical system according to a predetermined subframe sequence of holographic image frames, the filter performs spatial-angular filtering of the modulated light beam to exclude parasitic diffraction order components from the modulated light beam, and the electric optical scanner directs the modulated and filtered light beam towards a corresponding channel of the multi-channel projection optics and forms a plurality of viewing zones on a focal plane of a field lens provided in the screen.

Abstract: An optical device includes a light input part and a light output part. The light input part includes a micro display; a first and a second polarizing beam splitters configured to reflect or transmit incident light including an image displayed on the micro display; and a first quarter wavelength plate configured to receive light transmitted by the first polarizing beam splitter or the second polarizing beam splitter and change a polarized state of the received light. The light output part includes a third and a fourth polarizing beam splitters configured to transmit or reflect light including the image received from the light input part; a second quarter wavelength plate configured to receive the light transmitted by the third polarizing beam splitter or the fourth polarizing beam splitter and change the polarized state of the received light, and a light condenser configured to condense the polarized light.

Abstract: Provided are an optical switch and an imaging system using the same. The optical switch includes an electrically controlled optical shutter configured to alternately pass and block light beams incident thereon; and a prism array comprising prisms separated from each other by a gap and configured to deflect the light beams that passed through the optical shutter by a predetermined deflection angle, and being positioned on the optical shutter, wherein the optical shutter is configured to operate in a first mode of operation in which the light beams incident towards the gaps between the prisms of the prism array are passed and the light beams incident towards the prisms are blocked and a second mode of operation in which the light beams incident towards the gaps between the prisms of the prism array are blocked and the light beams incident towards the prisms are passed.
